X-RAY DETECTORS GO SOLID STATE
By H. W. Pickett, Manager — Application Engineering, Industrial X-Ray Products, XRay Department, General Electric Company.
General Electric now offers from stock a highly reliable, transistorized X-Ray detector smaller than the average table-model XV set. The new SPG 5 detector is fully compatible with most commercially available instruments. Its small size and light weight (only 60 lbs.) makes remote operation simple. The unit features both linear and logarithmic ratemeter response, preset time or count variable from 0.1 to 9,999.9 seconds or 100 to 999,900 counts. Full-front access of plug-in modules makes service a shap. For details, write for Product Data Sheet A - 4 9 8 6
NEW PET CRYSTAL GIVES APPROXIMATELY DOUBLE EDT INTENSITY
Pentaerythritol (PET) crystals now offered as stock items by General Electric, commonly provide 1.5 to 2.5 times the intensity normally obtained with E D T crystals. P E T crystals are usable with air, helium or vacuum spectrometers. They provide the same dispersion as E D T and are most efficient for elements Al to K. For details ask for Product Data Sheet A 4 9 8 3 E Page 1 .
AUTOMATED CRYSTAL CHANGER IS REAL TIME-SAVER
A new dual crystal changer that automatically positions either of two analyzing crystals in minutes is now offered for use with G-E SPG-2 and SPG-4 spectrometers. Besides time savings, this new changer gives precise crystal adjustment, reproducibility of setting over many thousands of changes and visual indication of crystal position. Handling of crystals is reduced to a minimum and helium atmosphere is not affected by crystal change. For complete specifications, ask for Product Data Sheet A 4 9 8 3 E Page 1 .
NEW REPORT ON AUTOMATED X-RAY SPECTROGRAPHIC ANALYSIS
A recent General Electric report discusses unattended operation of an automated X-Ray spectrograph capable of analyzing up to 11 elements on a total of 90 samples. Not only can peak values be programmed for element determinations, but also background values can be obtained by programming 2 Theta values consistent with the background obtained from the recorder. Consider the savings in operator time one of these proved G-E instruments offers. Ask for Publication 1 1 A - 3 9 6 1 .
